SPECFICATION forming part of Letters Patent No. 398,792, dated February 26, 1889.

Application filed May 26, 1888. Serial No. 275,141y (No model.)

To all whom it may concern,.- l Be it known that I, ALONZO OAKES, a citizen of the United States, residing' at Taylor, inthe county of Jackson and State ot' \Vis consin, have invented a new and useful linproveinent in Saws, of which the following is l a specifica-tion.

My invention relates to an improvement in buck-saws; and it consists in the peculiar conl struction and combination of devices that. will 3 be more fullyv set forth hereinafter, and particularly pointed out in the claim.

ln the accoirnianying drawings,Figure l is a side elevation ot' a portion of a saw-lillade provided with cutting' and clearing, teeth enibodvinej in v improvements. Fig. 2 a transverse seetional'viewof the saine, taken on the line .fr .fr oi' lfig. l. Fig'. $3 is a similar view laken on the line y y of Fig. l. Figui is an edge view ol.' my improved saw.

A represents a smv-blade, which is provided on ils lower edge with the forward] v-inelined teeth Il, the Vlower edges of which are bifu rcated to l'orm each a pair of V-shapedcuttingtongnes, Arranca-nl between eaeh pair of teeth ll is a clearing-tooth, l), which is likewise inclined forwardly, and has its lower edge, inclined rearwardly and upwardly, as shown, the front eide, lil, of each clearing-tooth being,r perfectly square, and thereby forming a chisel edge or point, F, at its lower corner. The length oi" the clearing-teeth l') is velv ,slightlwy less than Vthe length ot` the 'teeth ll. The said teeth l) and B are separated b v incisions ll of eorsiderahle depth.

The point-s ol each tooth ll have theirl edges ben-led on one side. so as to provide the said points` with sharp cuttii'lg-edges, and the bevels on each pair ol points extend .in opposite illireetions, one ot said points of cach pair being beveled on the right side, and the T other point being beveled on the opposite i side, thereby adapting the teeth B to eut both sides of the kerf. The said points C are also set orinclined laterallv in opposite directions. l

Then the saw is in opera-tion, the teeth B, being inclined forwardly, cause their points C to engage and cut in the bottoni of the kerf, thereby keeping` the saw continuously fed to its work, and preventing` the saine from moving back and forth in the kerf without deepening` the latter. 'lhe depth of the recesses H is such as to permit the sawdust to accumulate between the teeth l?) while the saw is moving through the kerf, and the function of the teeth D is to clear away the sawdust from the kerl", and thereby prevent the same from binding against the saw.

The recesses ll are further advantageous, inasmuch as theyv render it easwY to sharpen the enti ing-edges otl the points C b v means of a [ile7 and, owing1 io the angle between the liront and lower sides of the clearing-teeth D, the pointsl of said teeth may be readily kept Q sharpmied bv simply filing;` the lower edges of the said teeth.

llavinfa,l thus described my invention, I ela i ne 'lhe saw having;l the l'orw.irdl.\ inclined teeth l5, bilureated at the lower ends to form V-shapcd cutting-points C, the latter being.,r inclined laterally in ollposite directions and beveled orsharpened on opposite sides, and the forwardly -inclined clearing-teeth D, arranged one between each pair of teeth B, said clearing-teeth bein g' slightlhsv shorter than the teeth ll, and having` theirlower sides inclined upward and rearward, and provided at their lower front corners with the square chiseledges F, substantially as described.

In testimony that l claim the foregoing as nl v own l have hereto affixed in v signature in presence ot' two witnesses.

ALONZO OAKES.
